Google India has introduced a new feature which enables mobile users to send SMS to a specific number and get information back as messages. We can get a whole lot of information from stock price, PNR status of our train ticket to weather. You can see the detailed information from the google site http://www.google.co.in/mobile/default/sms/. If you are on the move, you can send a SMS with text "help" to the number 9-77-33-00000. In seconds, you should get a reply from the same number with information on what information you can get. This is not much useful unless you go to the site.
The site says that we get this service for the standard charge we generally pay for sending SMS from our mobile. I have tried a some things and I am getting replies back. For example, I send the message with text "stock hcltech" to 9773300000 and in some seconds I got a reply with the stock price. I have to check with the customer care or will wait to see my monthly bill. For customers having corporate plans most of which allows sending unlimited local SMSs, it would be very useful. Before using this, make sure with your mobile operator for the charges applicable for this.
